ABSTRACT:
A process is disclosed for producing L-threonine, the process involves culturing in a medium a microorganism of the genus Escherichia capable of producing L-threonine which has resistance to at least one of rifampicin, lysine, methionine, aspartic acid and homoserine, or a decreased ability to degrade L-threonine, accumulating L-threonine in the culture liquor and recovering L-threonine therefrom.
